Really?

I'd become accustomed to the dazzling variety of metal genres out there. Old school 70's metal, acid metal, black metal, death metal, speed metal, thrash metal, symphonic metal, power metal, folk metal...

Filed under not quite as "what the hell did I just watch" as my introduction to BabyMetal, it turns out there is, indeed, a capella metal. Or the next best thing to it.
